On the night of the 20th/21st the 11th R.B. were ordered to seize the crossings at Crèvecœur to allow French cavalry to pass through at dawn. The night was pitch dark, the men were exhausted, and Crèvecœur was found by then to have been occupied by the enemy. The battalion captured an enemy machine gun complete with team, but was unable to take the bridges. That night IIIrd Corps issued orders that every effort must be made to gain possession of the Beaurevoir-Masnières line and to capture Crèvecœur. The rôle of the Division was to push on to Crèvecœur in conjunction with the 29th Division on the left. The 59th Brigade was detailed to carry out this operation, with the assistance of twelve tanks, and zero was fixed at 11 A.M. on the 21st. Later, the attack of the 29th Division was cancelled. The tanks ran out of petrol, and eventually at 2 P.M. the 11th K.R.R.C., the assaulting battalion of the 59th Brigade, had to attack alone. The battalion came under enfilade fire from Rumilly and the high ground north of the canal, so that in spite of several efforts to force a passage during the day, little progress was made. That night the 11th K.R.R.C. consolidated a position on the spur north-west of Les Rues Vignes, while a company of the 11th R.B. held the bridge-head below the village. This company, owing to heavy casualties and to the impossibility of obtaining reinforcements, was ordered to withdraw during the night. Before doing so, the remains of the company, assisted by the R.E., made four gallant but unsuccessful attempts to destroy the bridge. The 11th R.B. formed a defensive left flank, covering the crossings south and south-east of Mon Plaisir Farm. Two batteries of the 92nd Field Artillery Brigade moved forward at daybreak to positions north-west of Lateau Wood and supported this attack under considerable shell-fire. In the evening they withdrew to a small re-entrant between Lateau Wood and the La Vacquerie--Masnières road, where they were joined by the rest of the brigade. The medical arrangements for the battle included an A.D.S. and a walking wounded collecting post at Gouzeaucourt, and advanced posts near Villers Plouich and on the Gouzeaucourt--Bonavis road just behind the front fine. After the attack other posts were pushed forward to the La Vacquerie valley, towards Marcoing and later to Les Rues Vertes. Wounded from many different divisions passed through the A.D.S. at Gouzeaucourt. Excellent work was done by the bearers of the Division under Lieut.-Colonel A. C. Osburn, commanding the 60th Field Ambulance.
